What polls. I’ve never seen a single poll that says that. Please post, it might be an interesting read.
WaPo - 18 July 08

Seventy-five percent of Americans in a new Washington Post-ABC News poll said gay people who are open about their sexual orientation should be allowed to serve in the U.S. military, up from 62 percent in early 2001 and 44 percent in 1993.
Pew Research Mar 2006:
The public supports a policy of allowing gays and lesbians to serve openly in the military by a margin of 60% to 32%. This represents significantly broader support for this inclusive policy than in 1994, when 52% favored allowing gays to serve openly and 45% were opposed.
